In this paper, we introduce the annular instanton Floer homology which is defined for links in a thickened annulus. It an analogue of Khovanov homology. A spectral sequence whose second page and converges to constructed. As application sequence, prove that detects unlink annulus (assuming all components are null-homologous). Another new proof Grigsby Ni's result tangle distinguishes braids from...

Successful clinical treatment of mitral valve disease is dependent on understanding the complexities of patient-specific valve behavior. Mechanical models of the mitral valve, designed to predict valve closure and generated using patient-specific measurements, have proven to be effective tools for studying valve behavior. To be clinically feasible, these models need to be generated from ultraso...

AIMS The purpose of this study was to evaluate a retrograde approach for radiofrequency (RF) ablation of ectopic atrial tachycardias (EATs) with an early atrial activation at the His site. METHODS AND RESULTS This study included 12 patients with EAT. During tachycardia, earliest atrial activation was recorded at the His site at a standard catheter setting. Activation mapping was performed in ...

Multidetector row computed tomographic (MDCT) assessment of aortic annulus dimensions and frame position and deployment have been associated with paravalvular aortic regurgitation (PAVR) after transcatheter aortic valve implantation (TAVI). The present evaluation investigated the (pre- and postprocedure) MDCT associates of PAVR ≥2+. In total, 123 patients referred for TAVI underwent clinical ev...

INTRODUCTION Mitral valve repair is the treatment of choice to correct mitral insufficiency, although the literature related to mitral valve annulus behavior after mitral repair without use of prosthetic rings is scarce. OBJECTIVE To analyze mitral annulus morphology and function using real time tridimensional echocardiography in individuals submitted to mitral valve repair with Double Teflon...

AIMS To evaluate the effects of applying current sizing guidelines to different multislice computer tomography (MSCT) aortic annulus measurements on Corevalve (CRS) size selection. METHODS AND RESULTS Multislice computer tomography annulus diameters [minimum: D(min); maximum: D(max); mean: D(mean) = (D(min) + D(max))/2; mean from circumference: D(circ); mean from surface area: D(CSA)] were me...

BACKGROUND Back pain and disc degeneration have a growing socioeconomic healthcare impact. Mucin 1 (MUC1) is a transmembrane glycoprotein whose extracellular and intracellular domains participate in cellular signaling. Little is currently known about the presence or role of MUC1 in human disc degeneration. METHODS In this IRB-approved research study, 29 human disc specimens were analyzed for ...

Accurate assessment of the aortic valve area (AVA) and evaluation of the aortic root are important for clinical decision-making in patients being considered for transcatheter aortic valve implantation (TAVI). Real-time three-dimensional transesophageal echocardiography (RT3D-TEE) provides accurate and reliable quantitative assessment of aortic valve stenosis and the aortic root. We performed tw...

When a chromatic (eg light-blue) annulus surrounds the central gap of an Ehrenstein figure so as to connect the inner ends of the radial lines, a striking new lightness effect emerges: the central white disk has both a self-luminous quality (brighter than in the regular Ehrenstein figure) and a surface quality (dense, paste-like). Self-luminous and surface qualities do not ordinarily appear co-...

Effective cuttings transport and accurate drilling hydraulics prediction remain issues of concern during operations horizontal, extended reach multilateral wells. While several studies have adopted a two- or three-layered modelling approach to evaluate efficiency, they neglected the effect gas-liquid fluid flow pattern within annulus on transport. An experimental theoretical study was carried o...
